Thanks for asking here! For this issue, we suggest you to re-install Trend Micro Maximum Security to reset the program and patterns. Since the issue you're encountering is related to Password Manager, which is bundled in Maximum Security installation, hopefully a reinstall will reset everything and remove the startup error. We have a support document which explains how to reinstall:Reinstalling the latest version of Trend Micro Security program

Are you using Password Manager regularly? If not, if the error still occurs, it will not impact Maximum Security's functions in any way. Though we understand it is annoying.
